Which of the following sequence is correct?

Options

A. Descending part of colon- Rectum Anus
B. Stomach Jejunum- Duodenum
C. ileum Colon Caecum
D. Colon- Anus Rectum

Answer

To determine the correct sequence of the parts of the digestive system, particularly focusing on the large intestine, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Components of the Large Intestine:**
- The large intestine consists of several parts: cecum, colon (which is further divided into ascending, transverse, descending), rectum, and anus.

2. **Understand the Sequence of the Large Intestine:**
- The sequence starts with the cecum, which is the first part of the large intestine.
- The cecum leads into the ascending colon, then the transverse colon, followed by the descending colon.

3. **Follow the Path to the Rectum and Anus:**
- After the descending colon, the next part is the rectum, which stores feces before elimination.
- Finally, the rectum opens into the anus, which is the external opening for the expulsion of waste.

4. **Assemble the Correct Sequence:**
- The correct sequence from the descending colon to the anus is:
- Descending colon → Rectum → Anus.

5. **Evaluate Other Options:**
- Other sequences mentioned (like colon, anus, and rectum) are incorrect because the rectum must come before the anus in the digestive tract.

### Conclusion:
- The correct sequence is **Descending part of colon, Rectum, Anus**.
